Review: Fits old Thetford toilet easy replace. - My toilet was smelling bad and figured it was the flange seal. My old one was worn out and distorted allowing gases front black tank to seep into the camper. These are super easy to replace so don’t feel intimidated not a dirty job. 1. Turn off the water and pump to your rig 2. Turn on few faucets to relieve the pressure in the lines 3. Hold the foot pedal down for a few seconds to dump all the water 4. Remove front cover around foot pedal “it just snaps on” 5. Unscrew water line on back of toilet mine just threads on by hand no tools needed. (Recommend getting a towel around water line, little excess water in the line will probably drip out. It’s clean water don’t worry comes from same place your sink does) 6. On each side of the toilet these is a nut you need to remove I think was 9/16 I just used adjustable wrench. 7. After removing nuts and disconnecting water line your toilet can be lifted off. I laid down a trash bag on the floor to set it on. 8. Replace gasket, old one will be either stuck to floor flange or on bottom of the toilet. Place the new one on the bottom of the toilet with the tapered part facing down towards the floor. 9. Set toilet back in place will be little tricky to line up the holes for the bolts. Ensure the toilet is centered on the hole and sits flush and straight. 10. Tighten down the two nuts. Don’t over tighten them, the flange and the toilet is plastic and will crack. Just snug is good. 11. Reconnect water line and turn water back on and your done. No more sewer smell.
